Is there a tort action brought against the Federal Trade Commission for failing to protect a mailman from a shooting?

As noted above, plaintiff also asserts some type of tort claim against defendants arising from the shootings that allegedly took place on plaintiff's mail route. Defendants correctly note that the United States is the only proper defendant for that claim. See FDIC v. Craft, 157 F.3d 697, 706 (9th Cir. 1998) (noting that the Federal Tort Claims Act ("FTCA") is "the exclusive remedy for tortious conduct by the United States, and it only allows claims against the United States. Although such claims can arise from the acts or omissions of United States agencies, an agency itself cannot be sued under the FTCA.").
